Title: Thumbnail File Size
Post by: Pasci on October 29, 2004, 04:54:11 am

Hello guys:

I was wondering why the file size of the thumbnails created by Coppermine with the use of Imagemagic are larger than the original size photos?
The original photo is 25kb and the thumbnail is 47kb. How can that be? Obviously, the actual viewing size of the original photo is larger than the one of the thumbnail. But the file size is inverse.  :\'(

From the ImageMagick website:

31. Why are my JPEG files larger than expected?

    Your JPEG files may contain embedded "profiles" such as Exif or IPTC, or they may contain uncompressed thumbnails. You can use the +profile "*" commandline option or an equivalent API method to remove them.

This can also happen if you are uploading gif files.
